Abstract
A lateral Metal-Semiconductor-Metal (MSM) Photodetector (PD) is based on amorphous selenium (a-Se). It has low dark current, high photoconductive gain towards short wavelengths, and high speed of operation up to several KHz. From processing point of view, a lateral structure is more attractive due to ease of fabrication as well as compatibility with conventional thin-film transistor (TFT) processes. The lateral a-Se MSM PD therefore has potentials in a variety of optical sensing applications particularly in indirect X-ray imaging utilizing scintillators and ultraviolet (UV) imaging for life sciences.
